44.Op Ar denominator
45.Sh DESCRIPTION
46.Nm Random
47reads lines from the standard input and copies them to the standard
48output with a probability of 1/denominator.
49The default value for
50.Ar denominator
51is 2.

53The options are as follows:
54.Bl -tag -width Ds
55.It Fl e
56If the
57.Fl e
58option is specified,
59.Nm
60does not read or write anything, and simply exits with a random
61exit value of 0 to
62.Ar denominator
63\&- 1, inclusive.
64.It Fl r
65The
66.Fl r
67option guarantees that the output is unbuffered.
